Over-protective father Ben Affleck

'State of Play' actor Ben Affleck, who has two daughters with his wife Jennifer Garner, admits he doesn't want to think about his kids growing up and dating

Ben Affleck is dreading the day his daughters start dating.

The 'State of Play' actor tries not to think about three-year-old Violet and three-month-old Seraphina - his daughters with wife Jennifer Garner - bringing home boys, adding he will be very protective of them when they do.

Asked how he will feel when his children begin attracting suitors, Ben replied: "I'm already planning on it - practicing the rocking-chair-and-rifle routine."

Ben is not the only celebrity father to discuss his children's prospective romances.

Before his twin daughters were born, Jerry O'Connell insisted no one will ever be good enough to date them.

Jerry - who has three-month-old twin girls Dolly Rebecca Rose and Charlie Tamara Tulip with his wife Rebecca Romijn - said: "I don't want them to date. They're only allowed to date men who run countries. They're only allowed to date men who are heir to the throne or are currently running a nation."

Benji Madden is also fiercely protective of his 13-month-old niece Harlow, the daughter of his twin brother Joel and Nicole Richie.

Benji explained: "I'm going to be keeping a close eye on her. I'll leave the shotgun right by the door."
